The PEP gives an example of enumerated members that themselves have methods. https://www.python.org/dev/peps/pep-0435/ There was another example somewhere (I don't remember where) of an enumeration of the planets, where planets can have attributes and methods: Planet.MARS.mass Planet.JUPITER.moons() which is no more weird than this: class Planet(Enum): MARS = "the red planet" Planet.MARS.upper() -- Steven D'Aprano "Ever since I learned about confirmation bias, I've been seeing it everywhere." -- Jon Ronson -- https://mail.python.org/mailman/listinfo/python-list
